To investigate the genomic origins, subcellular localization, and potential regulatory processing of unannotated long and short noncoding RNAs in the human transcriptome.
Conducted a genome-wide mapping study analyzing human nuclear and cytosolic polyadenylated RNAs longer than 200 nucleotides alongside whole-cell RNAs shorter than 200 nucleotides.
Assigned subcellular addresses to detected RNA sequences and evaluated their precursor-product relationships and potential processing into small RNAs.
Identified three novel, potentially functional classes of RNAs within the human transcriptome.
Found that two of the newly classified RNA types exhibit syntenic conservation across species and correlate directly with the expression state of protein-coding genes.
Demonstrated that unannotated pervasive transcripts serve as primary precursors for generating functional short RNAs within a highly interleaved genomic architecture.
